# Intro to Algebra and Equations

Today we are talking about Algebra. We watched the video below (particularly the second half of it) and observed the assignments below. We also used the smart board for algebra tiles. If you would like to try you can download the file below and get the free smartboard software to use with your mouse.

# Math – Adding and Multiplying Fractions

This week we are going to be adding and multiplying fractions. To get some help with this you can watch the Math Antics videos below.

The assignment:

Grade 7 – P. 179 – 5.1 Using models to add fractions

17.01.16 grade 7 – p.178 – using models to add fractrions

Grade 8 – P. 104 – 3.1 Using models to multiply fractions and whole numbers

17.01.16 grade 8 p.104 – 3.1 using models to multiply fractions and whole numbers

# Math – Integers

Today we are introducing integers. Students are to engage with the smart board files below (the software is free if you want to try from home using your mouse as opposed to touch screen). Then we will watch the video below and do some samples together in class prior to completing the assignments. Please see the assignment links and instructions below.

**Smartboard lesson materials**

17.01.09 Grade 8 – Integers 1 – coloured tiles

**Assignments:**

17.01.09 gr. 7 p. 56-59 – 2.2 adding integers with tiles

17.01.09 gr.8 p.64 – 69 – 2.1 using models of to multiply integers

**Assignment instructions:**

Please note that the grade 7 and grade 8 students have separate assignments with some cross-over.

-Grade 7’s must complete all of “2.2 Adding Integers With Tiles” (from the Gr. 7 textbook) and only the a’s in questions 1-14 of “2.1 Using models to multiply integers” (from the Gr. 8 textbook).

-Grade 8’s must complete only the a’s of questions 1-8 of “2.2 Adding Integers With Tiles” (from the Gr. 7 textbook) and all of “2.1 Using models to multiply integers” (from the Gr. 8 textbook).

-Note: we are not using coloured tiles as outlined in the instructions. Instead, students are asked to identify 2 colours of pen to use to represent in their work. For example: a student may use blue for positive numbers and red for negative and then represent tiles with squares or circles.

# Math – Surface Area and Volume of Rectangular Prisms

Be sure to watch these helpful videos on how to find the surface area and volume of rectangular prisms. These can be a big help.

Surface Area of a rectangle – this one is a little dry but it explains exactly how to do it in the way shown in the examples of the assignment.

This one is perfect for volume of a rectangular prism. Watch from 6:00 – 7:30 for how to find the volume of a rectangular prism.
